INTERNAL-COMBUSTION ENGINE.

Application tiled October 19,

T all 'whom it may concern.'

Be it known that I, PAUL C. ELLIOTT, a citizen of the United States, and a resident of Lawrence, in the county of Douglas and State of Kansas, have invented a certain new and useful Improvement inlnternal- L Combustion Engines, of which the folien passage of the motiv llit 1s a specification.

y invention is an improvementin ini ternal combustion engines, and has particnlar reference to the construction and arrangement ofthe inlet and exhaust ports and the valves therefor for eontrlling the e liuid to and from the engine cylinder.

An object of the invention n; to provide rotary valves for the different ports u1`-V l 4ranged in a novel manner, each rvalve being vention `matically grindin possible 4valve o Yin the cylinders'and the valves during a constructed with the end in view of autothe same, increasing the' ening, securing perfect .timing-due to the absence ofthe usual spring lag, and eil'ecting thorough scavenging vovvingto the simpllcityof construction.

The inventive idea involved is capable of 4receiving a variety of mechanical expres is a section on the line 2 2 of .complete operation thereof;

The cooling system includes n chamber'17'having a portion `formed in the apex of the cylinder head l2 and has branches 18 which cornmlnnicutc with the remainder of said '.iw inner walls of the cylinder head-.1 d in longitudinal section, as shown in'Fig. are preferably arranged at right angles to ich other to increase theY valve area in a given bore, and mounted in said cylinder head are the valve stems 20 of the .rotary valves 21 for controlling the ins take and exhaust. Each valve stem is probearings 1'9 in vided upon its outer end with a. beveled Worm orspirnl gear 22 with 'which' .meshes a suitable driving element-for rotating said gear and imparting asimllarmotion to the valve.
